Visual comfort is a long-facing problem in stereoscopic 3D (S3D) display. In this paper, targeting to produce S3D content based on color-plus-depth signals, a general framework for depth mapping to optimize visual comfort for S3D display is proposed. The main motivation of this work is to remap the depth range of color-plus-depth signals to a new depth range that is suitable to comfortable S3D display. Towards this end, we first remap the depth range globally based on the adjusted zero disparity plane, and then present a two-stage global and local depth optimization solution to solve the visual comfort problem. The remapped depth map is used to generate the S3D output. We demonstrate the power of our approach on perceptually uncomfortable and comfortable stereoscopic images.
视觉舒适度是立体3D（S3D）显示中一个长期存在的问题。本文针对基于颜色加深度信号生成S3D内容，提出了一种用于深度映射的通用框架，以优化S3D显示的视觉舒适度。这项工作的主要动机是将颜色加深度信号的深度范围重新映射到适合舒适S3D显示的新深度范围。为此，我们首先基于调整后的零视差平面进行全局深度范围重新映射，然后提出一种两阶段的全局和局部深度优化解决方案来解决视觉舒适度问题。重新映射后的深度图用于生成S3D输出。我们在感知上不舒适和舒适的立体图像上展示了我们方法的有效性。
